Plex transcoding used to be the problem, now it can save you terabytes of storage

Back in the day, we did everything we could to avoid transcoding in our Plex libraries.

But now that even cheap PCs can transcode video with ease, it's become a surprisingly useful trick for saving storage without having to buy more storage drives.
